Autorotate image based on EXIF Orientation tag.

Code

function imagecache_autorotate_dimensions(array &$dimensions) {

  // We can only know the resulting dimensions if both dimensions are equal.
  // Otherwise we need to inspect the image itself, which is not passed in here.
  // (this callback was introduced to enhance performance by NOT accessing the
  // image file when rendering the width and height attributes of the html img
  // tag).
  if ($dimensions['width'] !== $dimensions['height']) {
    $dimensions['width'] = $dimensions['height'] = NULL;
  }
